SYNTHESIS OF SIDEROPHORES BY SOIL BACTERIA OF THE GENUS Pseudomonas UNDER VARIOUS CULTURE CONDITIONS
The ability of six strains belonging to the genus Pseudomonas isolated from the rhizosphere of wheat to produce pyoverdin was examined. The studied strains demonstrated a varied level of production of the siderophore, depending on the culture conditions. The highest level of pyoverdin was determined after 72 hours of growth at 2025°C in iron-free medium supplemented with succinate. The synthesi...
متن کاملAdsorption of arsenic on soil under different soil moisture conditions
The adsorption study was conducted on three Japanese soils with different soil properties to characterize the adsorption pattern of Arsenic (As). Double tube method was used to find out the effect of soil moisture levels on As adsorption. For this study, besides double tube method, conventional batch method also was used. The As adsorption showed two phase kinetics. An initial and rapid adsorpt...

متن کاملSoil Properties, Nutrient Dynamics, and Soil Enzyme Activities Associated with Garlic Stalk Decomposition under Various Conditions
The garlic stalk is a byproduct of garlic production and normally abandoned or burned, both of which cause environmental pollution. It is therefore appropriate to determine the conditions of efficient decomposition, and equally appropriate to determine the impact of this decomposition on soil properties. In this study, the soil properties, enzyme activities and nutrient dynamics associated with...
متن کاملPotassium Fixation in Soil Size Fractions of Arid Soils
Najafi-Ghiri M., Abtahi A. (2013): Potassium fixation in soil size fractions of arid soils. Soil & Water Res., 8: 49–55. Amounts of potassium (K) fixed in soil fractions of 10 calcareous soils of southern Iran were measured to evaluate the contributions of different soil size fractions to K fixation. Soil particles were fractionated after dispersion of the soils with an ultrasonic probe. Potass...
